Dec 2019 Electric Bill

How does "winter" billing differentiate from the warmer months?

Living in Minnesota where the seasons are rather obvious, I honestly don't know how energy demand seasonally fluctuates for your region of the country.

 

we just got an offer for 22.5 cents/kwh for a 3 year contract vs 24 cents now.

 

Compared to yours, our monthly consumption is 3 times of yours @ 2 times more expensive electric rate /kWh.

 

straight cost, no monthly minimum. although, i have no idea if the cost would actually be zero if we shut the place down. they would probably come up with some charge or other.

 

There is a Service Connection Fee to have access. On Long Island we pay .21 per kwh so at the 25 miles per 8.8 kwh battery charge we pay 8.8 x .21 = 1.85 for a full charge to go 25 rated miles = 1.85 / 25 = .074 per mile. Gas at $2.75 gal / 52 mpg = .05 per mile.

However a full charge rated at 25 miles shows 29 on the display after a full charge and is 35 miles in practice with regeneration
Thus, 1.85 / 35 = .05 per mile on electric.

Charge Mode is great when gas is cheaper than electric or when you want a charge for stop and go traffic.
Driving a constant 30-40 mph in HV mode will recharge your battery and move you forward. Still looking for this sweet spot.

 

Just FYI, the full charge is not 8.9kWh, Even though that is the spec of the full capacity of the battery, most EV (including the Toyota hybrid) let you charge only up to ~85% and let you drain down to ~15%. For PRIME it comes out to be ~6.5 kWh for a full charge using L1 EVSE, and slightly less 6.1-6.3kWh using L2.

You are correct in that you can get more than 25 miles of EV most of the time, but that really depends on how and where you drive and temperature/weather. During summertime, I can get up 35 miles on my hilly terrain commute, but in winter sometimes it is less than 20 miles. Incidentally, my electric rate is very close to yours at $0.205/kWh, but gas is cheaper at $2.30/gal now. Gas mileage is also affected by the same variables so that in summer I can get above 65mpg easily but in winter sometimes dips down to 40mpg. On average 25miles EV range and 53mpg as reported by EPA standard for the PRIME is very close to my real average. On average, my HV comes out to be just about even with EV in terms of cost per mile at $0.55/miles.

 

Our utility would bill us a $25 a month system maintenance or service fee even if we used no power.
